GWO Optimized PI Controller Fed PV Based Interleaved Luo Converter for EV Applications

A significant role will be played by electric vehicles (EV) and renewable energy sources (RES) in the future as it relates to transportation and energy generation. However, the wide scale application of both these technologies requires an advanced power system architecture, especially in the form of an optimal design of DC-DC converters. An Interleaved Luo Converter (ILC) design is therefore suggested in this study to handle the issue of voltage conversion and control in these applications. The suggested converter type has a high voltage gain and minimal conduction loss, ripple and stress currents. Hence, the proposed converter design is effective in improving the life time of both PV and EV. This research also employs a proportional integral (PI) controller tuned using Grey Wolf Optimisation (GWO) to maintain the output voltage of ILC at a constant value. The credibility of the proposed converter along with controller is tested by modelling and executing its simulation model in MATLAB and by also designing a lab-scaled prototype of the ILC. From the derived results, it is confirmed that ILC functions with a remarkable efficiency of 97.5%.
